• Comments By IMO Board Member Bill Taylor - Market Surveillance Panel Report on Proposed Changes to IMO Information Confidentiality Catalogue (April 1-03)
The Panel was asked to assess the impact of releasing market data relating to unit specific generation output in near-real time, as well as planned and historic outages and maintenance of generators, aggregated by fuel type. It based its assessment on whether disclosure would increase or decrease the effectiveness of competition. The Panel concluded that concerns about releasing unit specific output information were not significant enough to warrant not releasing the information, given the present stage of the market's development. The Panel determined that the market data should be released at least an hour after dispatch, and that the impacts should be monitored as the market evolves.
